Amazing Simple Experiments That You Can Do In Your Home While Staying Home

Amazing-Simple Experiments by Achiever Dream Chemistry Tuition Centre That You Can Do In Your Home While Staying Home 

Hot ice

You can make it by adding vinegar to baking soda the result is a solution of sodium acetate when supercooled it crystallizes and heat is evolved, so although it resembles water ice, it's hot.

Dehydration of sugar

When you react sugar with sulfuric acid, the sugar is violently dehydrated the result is a growing column of carbon black, heat, and the overwhelming odour of burnt caramel.

Diet Coke and Mentos eruption

You can make it by drop Mentos into a bottle of Diet Coke.

The reason, the candies catalyze the release of gas from the beverage, which creates an eruption that pushes most of the liquid up and out of the bottle.

7 Layer Density Tower

Pour equal amounts of each liquid in the cups. All the amounts must be the same. You may want to set the cups in an order you’ll add them into the container (Honey, Corn Syrup, Dish Soap, Water, Vegetable oil, rubbing alcohol, Lamp oil)

1/ pour the honey into the cylinder carefully, Make sure the honey does not touch the sides of the cylinder while you are pouring. It’s important to let each layer settle before adding the next one.

2/ the next layer is corn syrup.

3/dish soap

4/ water use food baster let the liquids touch the sides of the cylinder. 5/vegetable oil use food baster again.

6/alcohol, Wash the food baster with some soap and water in the sink before moving on to the rubbing alcohol.

7/ lamp oil (rinse the food baster in the sink before moving on to the lamp oil.) (Since lamp oil is flammable, you must do this last step away from any open flames.) Use the food baster to draw.

The reason is density. Density is a measure of how much mass is contained in a given unit volume (density = mass /volume) so the bulk density has to go down and the light one has to go up.

Silver crystal

Suspend a piece of copper wire in, 1M silver nitrate in a test tube (If you coil the wire you will get high surface area and more visible growth)

Place the tube in a darkened location. Try to avoid high-traffic (high-vibration) areas.

Crystals should be visible to the naked eye on the copper wire after about an hour. ( but larger crystals and noticeable blue colouration of liquid will occur overnight).

Lava lamp

Material needed:

1/ a clean plastic bottle, try to use one with smooth sides

2/ water

3/ Vegetable Oil (or you could use Mineral or Baby Oil instead)

4/ Fizzing tablets (such as Alka Seltzer)

5/ Food Coloring

Instructions:

1/Fill the bottle up about 1/4th (1 quarter) with water.

2/Pour the vegetable oil in the bottle until is almost full. You may want to use a measuring cup with a spout or a funnel. You may have to wait a couple of minutes for the oil and water to separate.

3/Add a few drops of your favourite food colouring. Watch as the colour sinks through the oil. Did your drops of colour mix with the water immediately or float in between for a few minutes?

4/Break your fizzy tablet in half and drop part of it into the bottle. Get ready … here come the bubbly blobs!

5/you can even get a flashlight, turn off the lights and drop in another half tablet. This time shine the flashlight through the lava lamp while the blobs are bubbling.

The reason is, the oil floats on top of the water because it is less dense or lighter than water. The food colouring has the same density as the water so it sinks through the oil and mixes with the water. When you add the tablet it sinks to the bottom then starts to dissolve. As it dissolves it makes gas, carbon dioxide. Gas or air is lighter than water so it floats to the top. The air bubbles bring some colored water with them to the top. When the air comes out of the coloured water blob, the water gets heavy again and sinks. It does this over and over again until the tablet is completely dissolved.
